If you are asking about common comedic elements of Shakespearean comedies, below are a couple.

1. Comedies end happily in contrast to Shakespearean tragedies which conclude with death, normally the deaths of several characters.

2. Almost all Shakespearean comedies include wedding scenes. The Merchant of Venice has three marriages; Much Ado about Nothing focuses on the relationships of several couples. Audience members will recognize this element as a comedic technique. While Shakespearean tragedies often include weddings (Romeo and Juliet and Othello are examples), those weddings or marriages result in more conflict either socially or domestically.

3. The comedies include a significant amount of banter. Often it is between a couple who is romantically connected, but sometimes the banter is between the lower class "clowns" of the plays.

While these are not all of the elements common to Shakespearean comedies, they are the main ones.
